\IMPROVEMEN'I' m DAJMPING-APPARA'I'US ron corvjr'narnnssns.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom a ma/yconcem Be it known that I, ADOLPIIIIPEARL, of the ca county, and State of New York, have invented a new and improved Apparatus for Dampening Paperfor Copying; and .I do hereby declare that theofollowing is a full, clear, and exact description of the same,- reference being had to the accompanyingdrawings, forming a part of this specification.

The object of this invention is to provide for the more uniform dampening of paper for copying letters and other manuscripts; and the invention consists, firstly, in a leather-covered roller, carried within a suitable yoke, in combination with a capillary cushion, projecting fiom a water-bath, whereby a means is provided for a uniform dampening of the said roller.

Figure 1 represents a plan .view of myimproved appak ratus for dampening paper, as illustrated, with the lid or cover open, and

Figure 2 a transverse section of the same, illustrating the manner of operating the roller upon the cushion.

Similar letters of reference indicate parts in both figures."

corresponding Referring to the accompanying drawings A, is abox .or case, constructed of tin-plate, or other suitable material, of an elongated formation, and havingits interior divided into two compartments by means of a partition running lengthwise of the said box A. V I

B isa roller, of cylindrical formation, constructed of wood, or other suitable material, and having its. periphery covered with India rubber, or other suitable-elastic material, and, lastly, one or more layers of chamoisleather, or other absorbent material, cut'in strips, and I passing spirally or otherwise around the said periphery from one extremity thereof to the other. This roller B is hung to turn freely within suitable bearings, carried upon the. extremities of a yoke. O, which is provided. centrallyiwith a handle, 0, for manipulation thereof, substantially after the manner of the ordinary blotting-roller.

D is a cushiomof elongated formation, and of a length corresponding with that of the roller B. This-- cushion D is composed preferably of a cloth exterior purpose herein set forth.

and woollen filling, butrnay be composed of any other suitable materials, and secured by meansvof tacks, or

otherwise, .upon theupper side of a block, d, of wood or other material, of the same longitudinal and lateral dimensions thereof.

Pending from the extremities of the cushion D are conduits e, which maybe composed of, buckskin, cloth, or other porous substance, suitable for conduction of water by capillary attraction.

The block d of the cushion D is placed within the larger of the two compartments of the box or case A, which forms a'water-bath, so that the upper surface ofthe cushion D will reach to about level-with the upper edge of the said bath, and the said bath is filled about half full of water,-so that the lower extremities of the conduits or pendants e are submerged therein.

The smaller or other compartment of the case or box A is intended to receive the roller B when not m use.

In the operation of this invention, the roller B is held by the handle 0 of the yoke O, as illustrated in fig. 2, and caused to pass back and forth upon the cushion D, which, after having been moistened by pouring water over it, is kept moist by the capillary action of its conduits or pendants e, and by said con-,.

tact of the roller thereon, moisture is readily imparted therefrom to said roller. v

When the roller has been thus moistened, it is rolled over the paper, to which it impartsthe proper degree of moisture lmiformly all-over the suture, obviating the danger of blotting and smearing which resultsfrom the use of a brush. Y

have secured by Letteis Patent, is- The combination of the leather-covered dampening What I here claim as my invention, and desire to' roller 13, the moistened cushion D, and the water-bath in the case A, substantially as described, and for the ADOLPH PEARL. Witnesses:
